GEORGE E. TERPE, OF IVALSTON, PENNSYLVANIA.

BRAKE ATTACHMENT FOR CARS.

SPECIFICATION forming part of Letters Patent No. 732,604, dated une 30, 1903.

Application filed March 12, 1903.

To all whom it may concern:

Be it known that I, GEORGE E. TERPE, a citizen of the United States of America, residing device applied thereto.

at Walston, in the county of Jeiferson and State of Pennsylvania, have invented certain new and useful Improvements in Brake Attachments for Cars, of which the followingis a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in brake attachments for cars, and is particularly adapted to be employed in connection with mining-cars.

As is well known to those familiar with the conditions in coal-mining, the cars in which the coal is loaded in the mine are coupled toget-her and drawn fromthe mine generally up a slope to a tipple or other terminal, and frequently the rope to which the cars are connected breaks, allowing the cars to descend the slope and causing considerable damage, as well, perhaps, as theloss of life.

My improved device is adapted to be attached to the rear car of the train, and in event of the rope breaking or of any of the cars breaking the coupling the attachment will engage with the road-bed or cross-tiesin such a manner as to instantly check and hold the car or cars before the same have obtained any headway in their backward movement.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate like parts throughout the several views, in which- Figure 1 is a side elevation of a portion of a mining-car and track, showing myimproved Fig. 2 is a side elevation of a part of the inside of the car. Fig. 3 is a side elevation of a part of the car, showing a modified form of construction. Fig. 4 is a top planwview of the same. Fig. 5 is a detail perspective view of a modified form of stop. Fig. 6 is a detail perspective view of one of the staples or keepers employed with the form of construction shown in Fig. 1.

To put my invention into practice, I provide a stop comprising a bar 1, having a Serial No. 147,418. (No model.)

pointed end 2. This bar is pivotally attached to the car, and in practice it is attached to the rear car of the train and may be permitted to drag over the road-bedor may be held suspended in a manner shown in Fig. 3 of the drawings. This bar acts as a check or stop against backward movement of the car and in the construction shown in Fig. 1 is pivotally attached to the plate or bar 3, which is provided with slots to receive the keepers 4. These keepers I preferably make in a form shown in Fig. 6 of the drawings, passing the arms 5 5 thereof through plates 6 and 7, attached to the inner and outer face of the car side or wall and held by nuts 8, threaded onto the arms 5 5. Keys 9 are inserted through the keepers 4 to secure the arm or plate 3 in position. The bar in this form of construction, it will be observed, is.

readily attached and detached from the car, whereby, if desired, it may be detached from the car before the latter enters the mine andv readily attached thereto previous to starting the train of cars up the slope.

In Figs. 3 and 4 I have shown a modified form of construction, in which the bar 1 is pivoted at 10 to the side of the car and is held normally out of engagement with the track d u ring such time as the device is not requiredfor precautionary measures by means of the supporting-keeper 12.

In Fig. 5 I show another modified form of drag-bar 1, which may be employed in connection with the arm or plate 3. (Shown in Fig. 1.) This bar 1 has an overhanging flange 14, which will engage with the periphery of the car-wheel when the drag-bar is in the engaging position with the road-bed or tie to act as a stop. During the forward movement of the car it will be observed that the and road-bed and that any backward tendency of the car will immediately cause the dragbar to engage with the road-bed or ties and check the backward movement of the car or cars.

In the practice of the invention it will be noted that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, What detachably pivoted to the car and provided [5 I claim as new, and desire to secure by Letters with an overlying flange, as and for the pur- Patent, ispose described.

1. The combination with the cars, of a bar 4. In combination with a car, an arm or 5 detachably secured to said cars, and a drag plate, a staple securing said arm or plate to bar pivotally connected to one end of said the car-body, and a drag-bar pivoted to said 20 first-named bar. arm or plate, substantially as described. 1 2.
